Detailed Implementation

[0026] The following will refer to the appendix in the example of this utility model. Figure 1 -Appendix Figure 10 The technical solutions in the embodiments of this utility model are clearly and completely described. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0027] like Figure 1As shown, this utility model provides a technical solution: a sloping part positioning device, including a support plate 1, a first limiting strip 2 fixed to the upper end of the support plate 1, a second limiting strip 3 fixed to the side of the first limiting strip 2, a hydraulic cylinder 4 fixed to the lower end of the support plate 1, and a limiting block 5 fixed to the upper end of the hydraulic cylinder 4. The support plate 1 serves as the basic support structure of the entire device, providing installation positions for other parts and confining the workpiece M within a certain range, thus creating basic conditions for positioning the workpiece M. This improves the positioning speed and, in conjunction with the limiting block 5, ensures that the workpiece M can be accurately positioned at its upper end, which helps improve positioning accuracy, ensures subsequent processing quality, facilitates production line automation settings, and reduces labor costs. The first limiting strip 2, fixed to the upper end of the support plate 1, is mainly used to limit the workpiece M in one direction, preventing the workpiece M from displacing beyond the expected range in that direction, thus assisting in the positioning of the workpiece M. The second limiting strip 3 is fixed to the side of the first limiting strip 2, further limiting the workpiece M from different angles. Working in conjunction with the first limiting strip 1, it effectively constrains the positions of both sides of the workpiece M, preventing unnecessary displacement. The hydraulic cylinder 4 is installed at the lower end of the support plate 1, serving as a power drive component. Its telescopic movement drives the upper limiting block 5 to perform corresponding actions, thereby achieving precise positioning of the workpiece M. The limiting block 5 is the core component of this positioning device, accurately and firmly fixing the workpiece M onto the support plate M.

[0028] like Figure 2-3As shown, the limiting block 5 includes a pull rod 501 fixed to the upper end of the hydraulic cylinder 4, a block 502 fixed to the upper end of the pull rod 501, a pressure block 503 fixed inside the block 502, a push block 504 fixed to the side of the pressure block 503, a positioning block 505 fixed to the side of the push block 504, a first slide rod 506 fixed inside the block 501, a first spring 507 fixed outside the first slide rod 506, a second slide rod 509 fixed inside the block 501, a second spring 508 fixed outside the second slide rod 509, and a sealing plate 510 fixed to the lower end of the push block 502. The pull rod 501 is a component that connects the hydraulic cylinder 4 and the block 502, and plays the role of transmitting the power of the hydraulic cylinder 4, so that the extension and retraction movement of the hydraulic cylinder 4 can drive the block 502 and other related components on the block 502 to move in coordination. Block 502, as the main frame structure of the limiting block 5, provides space for the installation and fixation of numerous internal components such as the pressure block 503, push block 504, and positioning block 505, and also functions to compress the workpiece M. When block 502 moves downward, it compresses the pressure block 503. The pressure block 503, through compressing the push block 504, converts the vertical displacement into horizontal displacement and transmits it to the positioning block 505. The positioning block 505 then converts the horizontal displacement into vertical displacement, extending out of block 501 to contact the workpiece M, thereby completing the positioning. The first slide rod 506 provides a sliding guide track for the push block 504, ensuring that the components move in a predetermined direction during movement, avoiding deviations, and making the movement of the positioning block 505 more orderly and accurate. The first spring 507 provides power for the reset of the positioning block 505. The second slide rod 509, like the first slide rod 506, provides a sliding guide for the pressure block 503, enabling the relevant components to make accurate displacement changes along their prescribed paths, ensuring the coordinated movement of the entire internal structure of the limiting block 5. The second spring 508 provides the power for the pressure block 503 to reset. The sealing plate 510 is provided with a stepped hole 5101 corresponding to the threaded hole 5011 inside the block body, which is mainly used to seal the lower end of the block body 502 and other related parts.

[0029] like Figure 4 As shown, the pressure block 503 has a first sliding inclined surface 5031 inside, and limit plates 5033 are provided on both sides of the first sliding inclined surface 5031. A first countersunk hole 5032 is provided on one side of the first sliding inclined surface 5031. The first sliding inclined surface 5031 cooperates with the second sliding inclined surface 5041. By pressing the second sliding inclined surface 5041, the push rod moves laterally. The limit plate 5033 can be blocked by the sealing plate 510 to prevent the pressure block 503 from falling. The first countersunk hole 5032 is used to install and accommodate the second slide rod 509 and the second spring 508.

[0030] like Figure 5As shown, a second sliding inclined surface 5041 is provided on one side of the push block 504, and a third sliding inclined surface 5042 is provided on the other side. A groove 5043 is provided in the middle of the push block 504. The second sliding inclined surface 5041 is squeezed by the first sliding inclined surface 5031, which drives the push block 504 to move laterally, so that the third sliding inclined surface 5042 squeezes the fourth sliding inclined surface 5051. Since the push block 504 needs to move laterally, the sealing plate 510 installed at the lower end is screwed into the threaded hole 5011 through the groove 5043.

[0031] like Figure 6 As shown, the positioning block 505 has a fourth sliding inclined surface 5051 on its side, a limit strip 5052 at the lower end of the sliding inclined surface 5051, and a second countersunk hole 5053 at the upper end of the positioning block 505. When the fourth sliding inclined surface 5051 is squeezed, it drives the positioning block 505 to extend downward, accurately positioning the workpiece M. The limit strip 5052 ensures that the positioning block 505 is blocked by the sealing plate 510 during movement, preventing the positioning block 505 from falling. The second countersunk hole 5053 is used to install and accommodate the first slide rod 506 and the first spring 507.

[0032] like Figure 7 As shown, a support block 5012 is fixed inside the block 501, and a threaded hole 5011 is provided inside the support block 5012; the support block 5012 and the sealing plate 5011 restrict the movement of the push block 504, so that it can only move laterally.

[0033] like Figure 8 As shown, the sealing plate 510 is provided with a stepped hole 5101 corresponding to the threaded hole 5011; the stepped hole 5101 is used to connect the sealing plate 510 to the support block 5012 by bolts.

[0034] Working principle:

[0035] During operation, the first limiting strip 2 and the second limiting strip 3 are first placed in the groove of the support plate 1, such as... Figure 10 As shown, the workpiece M is placed in the groove of the base plate. At this time, the workpiece M cannot be well positioned because the contact position between the right side and the base plate 1 is on an inclined surface, and it will slide in the groove. The hydraulic cylinder 4 is activated to drive the block 502 to move downward. The block 502 presses the workpiece M downward, pressing the pressure block 503. The pressure block 503, through the pressing push block 504, converts the vertical displacement movement into the horizontal displacement movement and transmits it to the positioning block 505. The positioning block 505 then converts the horizontal displacement movement into the vertical displacement movement, and the extended block 501 contacts the left side of the horizontal bar on the upper left side of the workpiece M. At the same time, the trapezoidal structure at the lower end of the block 502 will enter the area between the two horizontal bars on the upper end of the workpiece M, pressing the workpiece down. Because the right side of the support plate 1 is on an inclined surface, the workpiece M will move to the left. At this time, it will be restricted by the extended positioning block 505, thus completing the positioning.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
